If you’ve ruled out pests and weeds as the problem causing unsightly patches in your lawn, then it’s time to examine common lawn diseases as the culprit.

The following is a list of common lawn diseases that will affect even the best of lawns if not taken care of upon the first sign of disease.

1/ Brown Patch Lawn Disease

Brown Patch Lawn Disease

“Brown Patch” is also called a summer patch. It kills a circular area of the grass up to 2 feet in diameter. The infected area will change color and develop a likeness to the frog’s eyes, having a circular spot surrounded by a discolored ring of grass. The grass in these patches will probably be thin.

The problem causing the ring is a fungus that flourishes in the warm temperatures and especially with damp conditions caused by thatch. Excessive nitrogen fertilization and poor drainage encourage the disease. St. Augustine grass is particularly vulnerable.

If your lawn is infected with “Brown Patch”, apply a flowable sulfur fungicide to the infected areas every three to five days until the symptoms disappear. Make sure you remove any underlying thatch with a rake or dethatcher to avoid the problem from reoccurring. Also, avoid applying heavy doses of nitrogen fertilizers to your lawn and improve drainage if necessary.

2/ Dollar Spot

Dollar Spot

Dollar spot is named as such because it creates a tan or straw-colored spot in your lawn the size of a silver dollar. The dollar spot is a fungus that thrives on dry, undernourished lawns. Infected lawns will show small, white, cobwebby spots in the morning that turns brown later in the day. These patches will grow together to form larger patches.

The best way to treat a dollar spot is to apply a flowable sulfur fungicide to the infected areas every three to five days until the spots are gone. Frequent light applications of nitrogen will help your lawn recover after treatment, and regular mowing will cut the tips off of the infected grass, eventually eliminating the damage created by the fungus.
